Currently, libyuv supports MIPS SIMD Arch(MSA),
but libyuv does not supports MultiMedia Instruction(MMI)(such as loongson3a platform).
In order to improve performance of libyuv on loongson3a platform,
this provides optimize 98 functions with mmi.

The CpuId function is a wrapper for the intrinsic, or
implemented with inline if unavailable. It had been
using uint32, but the intrinsics use int, so it was causing
casting and lint warnings. This change makes the internal
implementation use int.
Casting was also done for xgetbv, and the cast is simply
removed, and is not causing a build error.
MipCpuCaps was doing strlen to check for white space after the
instruction set. Arm also does this but with a hard coded offset.
This was causing a cast from size_t to int, which produced a lint
warning. The change removes the white space detect.
In theory the code could be used to detect SSE vs SSE2, and it would
need to check SSE is followed by a space or end of line. But this
code is only used on Arm and Mips, where there there is one form
of SIMD detected. e.g. MSA for mips. If a new instruction set is
added with a similar name, the write space check could be reintroduced.
But its more likely the code can be rewritten to use a better form
of detection by then. Or remove detection and require the instructions

When attempting to normalize function names to end in Row_SIMD it was made
harder with MIPS_DSPR2 naming convention.
Other CPUs do not include the vendor. This should be named consistently.
Removed the DISABLE_MIPS in favour of DISABLE_ASM for consistency with other
processors.
